What's the weather and temperature trend this year?

First, large-scale warming.

Research data show that the annual average temperature in China has increased by 0.5-0.8℃, which is slightly higher than the average level of global warming in the same period, especially in the last 50 years.

From the perspective of geographical distribution, the climate warming in northwest, north and northeast China is obvious, and the national winter warming is the most obvious.

From 1986 to 2005, there were 20 national warm winters in China.

Second, regional precipitation changes fluctuate greatly.

Third, in the past 50 years, the frequency and intensity of major extreme weather and climate events in China have changed significantly.

The drought in North China and Northeast China is aggravated, and the floods in the middle and lower reaches of the Yangtze River and the southeast are aggravated.

Fourthly, in the past 50 years, the average annual sea level rise along the coast of China is 2.5 mm, which is slightly higher than the global average.

Fifthly, the mountain glaciers in China are rapidly retreating, and there is an accelerating trend.

The prediction of scientists in China shows that the trend of climate warming in China will be further intensified in the future.

Compared with 2000, the annual average temperature in China will increase by 1.3-2. 1℃ in 2020 and 2.3-3.3℃ in 2050.

It is particularly noteworthy that although the greenhouse gas emissions in China's history are very low, and the per capita emissions have been lower than the world average, from 65438 to 0994-2004, the average growth rate of the total greenhouse gas emissions in China was about 4%, and the total greenhouse gas emissions now rank second in the world, which inevitably aroused the concern and pressure of developed countries.
